Analysis: The computer is composed of hardware and software, and it is operated by users, so its running speed depends on whether the three can be optimized and coordinated, so it is impossible to solve the problem just by replacing a certain hardware. Although your hard disk is only 80G, it is 7200 rpm, which is fast in mechanical hard disk, but it may be used for a long time, and there may be fragments or bad tracks.

There are many reasons for computer card slowness, such as too many startup programs, security software background detection or database upgrade, virus infection, too many hard disk fragments, insufficient running memory caused by running multiple large-scale software for a long time, using Thunder to download at full speed and so on.

Treatment: It can be solved from three aspects:

1, hardware:

Compound or isolate the bad track of hard disk.

2. Software:

(1) Increase the running memory. You can use 360 security guards or software with similar functions to regularly clean and optimize the computer to remove unnecessary boot-up programs and various plug-ins.

3, operating habits: develop good computer operating habits, do not run multiple large-scale software at the same time, close unnecessary programs and windows in time, clean up the memory in time, and so on.
